I'm kinda thinking the conclusion was let it warm up a couple minutes and drive on?? Not sure, but anyhow I wanted to mention for me after the crossover ports were blocked, this has been a bear to keep running after a cold start. When it gets 20 or 30 here in KC iif I have to drive her somewhere then she not too happy about it unless she gets 5 or 10 on the warm up. Am I missing something on that mod?

Tom,
By next winter, I will know more, but I suspect that you are partly correct. My experience is not with an Olds 455, but I have run more than a few V-8s that did not have the heat riser in the intake manifold. They are always "cold blooded". One of the things that I know you will need is the thing called a warm air stove and damper in the intake horn. While these were mostly unneeded, with the cold intake, they may now be needed.
There is another thing that is sort of hidden. If you are running the choke element off the alternator output, you may need to look up and get the temperature switch so it does not open too soon.
As said, ask me again next year.
